ABSTRACT:
A video camera including a motion detecting circuit in which correlative values of pixels at a present field are evaluated through the comparison of an image signal of a last field and an image signal of the present field. In the motion detecting circuit, an average correlative value and a minimum correlative value are further evaluated. A microcomputer determines whether or not these correlative values satisfy predetermined conditions for each of detection areas defined within an image field. A detection area which satisfies all the predetermined conditions becomes a valid detection area. A whole motion vector is detected by methods different from each other according to the number of the valid detection areas.
